Hi, I recently bought a Samsung SGH-D307 from a friend. The phone is originally made for cingular but it had been unlocked for use with T-Mobile, which is the service I currently have. The phone is working fine, but the huge problem is that I cannot connect to any wireless web functions such as AIM, downloading ringtones, wallpapers, games, etc. I get an error message and cannot connect. With my old tmobile phone i could easily connect. I wondering if this is because the phone wasnt originally made for tmobile.. hopefully someone can help me
