Hi, My Ppc Boots Up And All Functions Are Working Properly Except The Phone Function .. I Put In A Sim Card And It Does Not Connect To My Network, When I Goto Start --> Settings --> And Click On Phone. The Phone Just Restarts Each Time. Someone Please Help!

The phone was originally setup to use only an AT&T Wireless SIM card. What are you using? The phone will ask for the subsidy code if it is not unlocked but the other functions should still work. I am currently using my PPC4100 as PDA only since I no longer have an AT&T Wireless account. I unlocked the phone but I did not go through the trouble of trying to get it to work with Cingular because it does not have MEdia Net capability. It is too uncomfortable to use as a phone because of the shape. Look for a replacement on eBay. You might have tried to update with the incorrect ROM upgrade.
