So I wasn't receiving text or calls on my iPhone 4 but I could call and text. called AT&T ask if there's any roaming problems, she said no. My iPhone was Jailbroken I didn't want to go get a replacement I loved my Jailbreak, but this was a serious issue so w.e I went. yes got a replacement not happy since I'm loosing my Jailbreak, get home with new iPhone happy guess what ? I STILL CAN'T receive call or texts! I called AT&T five minutes ago "were having roaming issues in your area wait 72 hours". Yea FML lost my Jailbreak, wasted gas money all that for no reason -_-. A tip the guy told me next time don't bring it with cydia there's some Aggy people working here who would make it void your warranty lol. who's going to be the first one to say sad story bro ?
