    Last week, i was upgrade my iPhone 2G to version 3.0

    i found that my iphone get hot everytimes ,

    only 4~5 hurs standby time after fully charge.

    On the other hand, iPhone was unable to receive phone call sometimes ,

    also SMS . even the Signal Strength was shown as Maximum !!

    so what is the problem ?

    i found two things to prove ,

    First , while i am putting my phone on my laptop ,

    some "Zi ... Zi .... Zi " sound was out from my earphone ( loudly ) !

    P.S. 1 ( Earphone is connected to my laptop )

    P.S. 2 ( Already turn off the Push Message and Wi-fi )

    after i downgrade to 2.2.1 , no more sound come out ! .....

    Second , while i am playing Need for Speed , it is very very lag ,

    after i switch to airplane more , no more lag !!

    ....

    All in All , i think that Apple was made a big mistake on the Firmware Network

    Modules , it will cause iPhone send out the Signal ,

    Non-Stop and Fully Power. so it is the reason why my iPhone is hot , Short

    Standby time , Unable to receieve a call , etc

    i hope Apple will fix it as soon as possible .

    same here, I'm charging my phone 2 or 3 times a day. I make maybe 2 5 minute calls a day,send 2 sms, and do 5 minutes web browsing.

    I have wifi, location services and notifications on.

    Even with the usage and setup above I should get more than 4 hours standby.

    It's not just the 2G, same here on 3G. My battery drains very quickly and heats up alot when you charge it.
