BLiNK with just almost 4 weeks to go for iPhone 5 announcement I think this could be last beta before GM, but, if we take into account that 3 weeks will be gone after Beta 4 release by August 27th, a Beta 5 won't susprise me nearly ready to release GM for September 12th. By then will have spent two weeks.
