It sounds like its a software problem and if you have only had it for about 5 months it should still be under warinty. Try calling your provider and tell them whats going on and see if they can send you a new phone.

When My Phone Did That, I Took It Into Metro And They Sent It In A Replaced It With A New One, The Guy At Th e counter Said That This Is A Common Thing And That Sometimes If You Download Anything From Your Phone Like From Funformobile.com Or Something, Or If Someone Sends Them To You From Websites Like That It Voids Your Waranty And It Causes That. I Hoped This Helped You, So Just Take It Into Metro And They Should Send You A New Phone Within 4-5 Buisness Days.

If you flashed the phone yourself then I assume you have software on a pc or laptop such as CDMA workshop or QPST configuration. If you do and you have the phones USB drivers on your computer all you have to do is put your phone in diagnostic mode and run one of these programs to access service programming. There you can change the sprint data settings to metros. For instance user name would change from old#@sprintpcs.com to new#@mymetropcs.com. It sounds difficult but if you know the settings and have the software it is quite easy.
If you paid someone to flash it for you, they did a half a$$ job as they should have done it during initial flash. You can google metropcs data and mms settings to get correct info.
