I've a problem with my new iphone 3g this week with it losing sometimes as much as 30 minutes in a day. If I put it in airplane mode and take it out, it resyncs it's time with AT&T and all is well. I've heard that I may need to take my phone in to have it looked at. Any ideas?

MacBook, Mac OS X (10.5.4)

    I have a first generation that will be out of warranty in about a month.. and for a few weeks now it has been losing time.

    Seems to be when it hibernates on battery power, it loses the time.. then hitting the home button to bring the screen up.. I usually see the clock sort of fast forwarding to the current time.. but it stops short (anywhere from an hour to 10 minutes behind the REAL time)

    But if I leave it plugged in to a power outlet (computer or wall) it doesn't lose time??

    I thought this might be the latest update bug.. but my wife has the same phone and hers doesn't do this.. and I have friends with the 3G and they have not seen this either.

    Guess I will make an appointment at the Apple Store

    Sounds like it may be a battery issue... I've seen very strange things with laptops and defective batteries, even when plugged in. Before the trip to Apple, fully discharge and fully charge the battery. Also, reset the iPhone by holding the sleep and home button until you see the apple logo, ignoring the slider. Another option is a restore from iTunes. If these don't solve it, visit Apple.

    Here is a good article to look at:

    How to verify iPhone hardware is working correctly

    If that doesn't resolve the issue, it may be time for service. You can set up mail-in service by phone at 1-800-MY-IPHONE (1-800-694-7466), or by visiting an Apple Store. To make an Apple Store reservation, visit http://www.apple.com/retail/

    Hope this helps,
