Hey guys . I have an iPhone 4G with iOS 5. I remember myself googling around a reason why i could not seem to have send mms , when i recall sending some the first 3 months within purchase . The mobile carrier is not AT&T (although it should be ) its actually H20. When i googled why i could not send any mms they said i needed to download cydia . I jailbroke it and now i don't know where to continue . Is this real ? Is cydia really helpful ? Or was it a sham ?
