i just got a mytouch 3 weeks ago and just 2 days ago, when i turned my mytouch horizontally to use the long keyboard it doesn't budge! also when i want to watch videos or look at pictures and i turn it horizontally, it won't move! i've been taking good care of it, i dropped it twice but there are no visible damages nor did it turn glitchy for a second. i love my mytouch but now i'm upset because i can't view anything horizontally? what do i do??
