Hi, Just wondering if there is a tweak out there to choose which contacts (by default) to send messages via iMessage and which to default via SMS. OR alternatively, a tweak to reduce the time delay until an undelivered iMessage sends as SMS (automatically). I have a few contacts with iPhones running iOS5 (iMessage enabled) - but they live in poor data signal areas with no wi-fi. Often, my messages will not deliver until 5 minutes later (when phone realises the iMessage hasn't been delivered and thus switches to SMS). Obviously I can hold down and choose 'send as text message' but I'd like a way for the phone to do this for me. So, does anything like this exist? If not, someone develop it please! Would be greatly appreciated.
