okay so iv had my sprint hero from day 1 and till this day i CANNOT delete my texts from anyone. if i try, my phone just crashes. my phone is sooo slow and my gf is such a snoop on my phone and i want to delete my texts from other people !!!! i downloaded Delete Old Messages and i always try and delete stuff. ill do like 1 month old. it will try and delete them all, like around 3,000ish and i will leave the phone alone for like 4 hours and only around like 30 will be deleted. =(
