I purchased the LG Optimus T P509 from T-Mobile. I unlocked it officially for AT&T, it is for my sister who wanted an Android but no data plan. It is perfect for her. She loves the keyboard, gets great service, nice texting interface, but she can't MMS! I went into settings and set-up the AT&T APN, and the AT&T MMS APN. The phone was going onto mobile data and to prevent her getting a high bill, I turned off mobile data. With a mobile data block there is no MMS! So I bought this app called APNDroid. I said keep MMS enabled, turn APN off. MMS doesn't work. APNDroid worked on my phone. However, my phone is a carrier unbranded Gingerbread phone.
PLEASE HELP! I have been looking high and low for months. Any help is appreciated
