Everytime I send and recieve a text message i get that error. i have options to force close or wait. if i put wait it seems to work fine. the phone is very sluggish. i have 245mb left on the phone and 3.59gb left on my sd card. i have one thread with 4000 messages and a few with 50+ and a few with 20. i am not sure if it has to with how many messages i have. also my phone is very sluggish most of the time. i have turned off and on my phone, took out the battery. i dont have many apps downloaded. is there anyway to get rid of this error without hard reseting my phone or taking it to tmobile store? thanks in advance.
