iPhone Losing Signal?

[Fhadso]

Ok, I have an iPhone 3G with 2.2.1 (Jailbroken) and lately I've been losing signal for no apparent reason. The are I live always has full signal and I rarely lose a signal. Is everyone having this issue? It's starting to piss me off because when I'm talking to someone my call gets dropped for no real reason. SHould I take it to AT&T or call apple and ask them about it?

How recently have you rebooted your iPhone?

Other things you can try before taking your phone in:

1.
toggle airplane mode on
power off phone
power on phone
toggle airplane mode on

2.
Check to see if your sim is not loose. You can also place a small piece of tape on the back of the sim to make it fit tighter in the tray.

Back in the 2.0 up to 2.2 days i had this issue and had 2 replacements at the Apple store for it - i was being told at the time it was software related but i still am more than certain it was hardware.

However, no real problems getting a replacement at the Apple store from the genius - was very helpful.

Now if only there was a local Apple store! Gah....thanks for the help, I'll post again if the problem persists...
