I am writing this on location with an actual iPhone 3G, and I must say, it is a pretty nice device. Looks and feels similar to the original but a bit lighter in weight. The 2.0 software interface is nicer than any of the previous ones, and applications are impressive especially in the graphics they have- which are above and beyond anything ever seen on a cellphone. The new black case is a fingerprint magnet, so be careful when you use it, and maybe even go out and get a case for it. Overall, I think this is a very worthy successor to the original iPhone based on my quick first look at it.

Ok, that was a little first take. Stay tuned as Aidan should soon have a review up on his on own iPhone 3G once he gets it in the coming days. In the meantime, how have your experiences been with the iPhone 3G and/or the 2.0 software on the iPhone 1 or iPod Touch (that is of course assuming you were able to get it from iTunes and onto your iPhone or iPod Touch). Also any apps you guys would reccomend for other users from the App Store? Let us know in the comments.

Reserve battery: Nokia instrument comes with a reserve battery. To activate, press the keys *3370# Your cell will restart withthis reserve and the instrument will show a 50% increase in battery.Thisreserve will get charged when you charge your cell next time.

Turn Down Screen Brightness: The screen is one of the most power-consuming parts of the mobile phone. The lower the brightness, the lesser power it needs. Keep it as low as you can, so long as you can still see it! Also, some phones like the E61 and the BlackBerry Pearl come with auto-adjust features that increase the brightness in brightly lit areas and dim it in low-light areas. If you’re setting the brightness low, make sure that auto-adjust is turned off.

Don’t Use Animated Wallpapers or Screensavers: The animations in wallpapers and screensavers can drain a bit of battery as they also consume a wee bit of CPU. Turn them off.

Turn Off Keypad Lights: If you’ve been using the phone for a while, you may be able to use the keys without seeing them. If this is the case, the keypad backlight can be turned off. However, not a lot of phones support this, but it’s worth considering if your phone does.

Decrease Screen Standby Time Out: The time till your screen dims out and/or gets turned off is configurable in most phones. 10 seconds is good, 5 seconds is better. Set it as low as you can go without it becoming inconvenient.

Close Background Applications: If you’re using a Smartphone, close applications that you don’t need. Applications that stay active in the background use up a bit of CPU, which uses up battery. Make sure you ‘exit’ the applications from the menu, not by pressing the ‘End’ key, as that merely puts the application in the background. In Series 60 Smartphones (mostly Nokias), hold down the ‘Menu’ key to get a list of all applications running in the background to close them. In Windows Mobile 5 phones, open the ‘Memory’ application and check the ‘Running programs’ tab to close them.

Turn Off Vibration: Probably the second most power-consuming feature of any mobile phone is the built-in vibration alert. See if you can do without it.

Turn Down Ringer Volume, Keypad Tones and Speaker During Calls: If you’re mostly indoors, like in the office or at home, a low ringer volume can go a bit towards saving your battery. Most phones also have DTMF-like keypad tones, which are not necessary if the keypad has decent tactile feedback. I keep them turned off most of the time — you can try it too. Volume of the earpiece when you’re on a call can also be lowered, and that helps too.

Disable Voice Clarity / EFR / Voice Privacy: Almost all phones now do Enhanced Full Rate (EFR) for voice communication that consumes a little more power. In most cases, the enhanced quality of EFR doesn’t make a difference thanks to the high noise levels in our city. Keep it off, you probably won’t miss it. Some phones (mostly Samsungs) have a ‘voice privacy’ feature which can also be turned off to save battery.

Turn off 3G / GPRS / EDGEMost 3G/UMTS/WCDM: A phones keep searching for 3G coverage by default. In India, they’ll keep searching till 2008, draining your battery, so go to the network selection screen and choose GSM-only. If your phone has a secondary camera near the screen, it’s a 3G phone. Check your phone’s specs on the website if you aren’t sure. Sometimes, even regular GPRS or EDGE connections stay active in the back, so make sure you specifically disconnect when you’re done browsing the web.

Use Bluetooth and WiFi Only While Transferring: If you only use Bluetooth occasionally to transfer files to and from other devices, there’s probably no point keeping it on all the time. Most phones only come with an on/off setting for Bluetooth, unlike the ‘Turn on for 10 minutes’ setting available for Infrared in some phones (mostly Sony Ericssons). People tend to forget about Bluetooth being left on after transferring the file — avoid doing this. Same goes for WiFi, if you’re phone has that.

Here’s another tip — find a USB cable if your phone supports recharging via USB: The Motorola RAZR/KRZR/SLVRs and most Windows Mobile Smartphones have a standard miniUSB slot that can use the same cable as most digital cameras. You’re more likely to find one of these lying around somewhere than a charger for your phone, unless it’s a Nokia, of course.

Finally, if you’ve tried everything else above then the only remedy will be don’t use the phone too much.

A friend shared this mobile codes with me so I also might as well share this to all of the readers of this blog.
