iPhone 4 Text Message Problems
About half of the texts that I send to one particular friend come through to him as just boxes, and about half the texts I send to another friend come through to her with every other character being upside down question marks...
So far, it only happens with those two people and it only happens with about half of the texts i send, and there seems to be no consistency for a reason (no particular length, special characters, etc.; they are not even both using the same service). Sent and received messages look fine on my end.
Any idea of how to prevent this or fix it?
