I upgraded to the ios7 when it first came out. Unfortunate for me. Now my phone is extremely slow and constantly freezes. It has even sent a few random blank text messages on it's own. I am becoming incresingly frustrated with the phone. I haven't even had it a full year yet. I have tried the *228 and updated my roaming. I even looked up a few tricks online and tried shutting off random things on the phone. Nothing seems to help. Is there anything I can do? I am seriously considering looking into other carriers to get out of my phone. I dont think I will ever buy an iPhone again at this point!
