After using it for a week, I have come to conclusion that the iPhone 3G is not quite what I expected to be (in not so great way). There are many shortcomings on it including battery life and lack of copy and paste functionality. While not all Apple’s fault, 3rd party applications need tighter quality control; many applications are crashing too frequently.

Apple said copy and paste function are not on their priority to-do list – without this feature, the iPhone 3G will not be suitable for writing documents, thus we won’t be seeing mobile office suite for it anytime soon.

Apple did publish a guide to conserve battery, but it contradicted the purpose of getting iPhone 3G - suggesting users to save battery life by disabling the 3G connection and use EDGE instead. I found this recommendation quite funny, especially for those who have 3G coverage.

From my daily personal experience, using push email, taking around 75 minutes of calls and surfing the web for roughly 20-30 minutes will put my battery life at 10-percent by 5pm (from 8am). Compared to the first generation of iPhone (without push email of course – but IMAP checks every 15 minutes) I still get around 16 hours of battery life. I think iPhone 3G external batteries would be something I look into buying in the near future, but for now I’ll just have to carefully manage my power usage.

If you are getting weak signals using 3G connections, you are not alone; many of iPhone 3G users experienced the same thing. I honestly can’t point finger on Apple for this one, it seems like AT&T’s 3G networks is flooded. Turning your 3G connections off and reverting back to EDGE seems to put all the signal bars back.

Tell me your iPhone 3G-experience, you can email it to me or just post it as comment below.
