Sony Ericsson :: Satio - SMS And MMS

I got my satio in may and didnt even have it for a month before things went wrong. firstly, i was never able to send a MMS to a virgin mobile phone. and then i wasnt able to send a text message to anyone. i called SE and they did all this stuff and called my carrier AT&T and nothing was wrong with my service because i put my SIM in my old phone and was able to send MMS and SMS. so SE said i had to send my satio in for repair(why they didnt just replace the phone i have no idea) and now i am waiting for parts. its been 2 weeks since i sent my phone in. and now i hear there isnt going to be another update? theres slight problems with this phone that if were fixed, it would beat the iphone and droid by a mile. i was just getting used to my satio and then i had to return it. they say i probably wont get it back until the 8th of july. thats just crazy in my opinion. why didnt they just replace the phone? when i looked into the satio as my new phone it looked so cool and when i got it i was so amazed by it. i even got a manuel in a different language, had to call SE and they said they wont send me an english manuel and that i should just look it up on their website since they update the software a lot...well apparently they dont since they havent updated it in months. to say the least, i am disapointed in SE with their future of the satio.
