My iPhone 4 on ios 5 has been sending the same text multiple times. Sometimes even 5 times. When i message someone, on the top it would say "sending 5 of 5". Sometimes it wouldnt even say it and the person who I texted tell me they get my texts 3 times. This has been a recurring issue since beta 1. On ios 4, sometimes i wouldnt get my friends texts.
