I have been looking at the Palm Centro black :a href="http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device=Palm%C2%AE+Centro+-+Obsidian+Black&q_sku=sku1260003" rel="nofollow"http://www.wireless.att.com/cell-phone-s…/a or blue: a href="http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device=Palm%C2%AE+Centro+-+Electric+Blue&q_sku=sku2650219" rel="nofollow"http://www.wireless.att.com/cell-phone-s…/a , the Blackjack 2 in Blue a href="http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device=Samsung+Blackjack+II+-+Blue&q_sku=sku2690222" rel="nofollow"http://www.wireless.att.com/cell-phone-s…/a , the Lg Vu a href="http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device=LG+VU(TM)&q_sku=sku2490219" rel="nofollow"http://www.wireless.att.com/cell-phone-s…/a , and the Blackberry pearl a href="http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device=Sandstone+BlackBerry%C2%AE+Pearl+8110+-+Pink&q_sku=sku3000338" rel="nofollow"http://www.wireless.att.com/cell-phone-s…/a . But i dont really like how the blackberry pearl has the 2 key thing; i'm not sure if ill like that phone because ill be using a lot of texting. I will be using my phone for TEXT MESSAGING, calling, camera, but no internet except to get ringtones. So please help me! Which one do you think looks the best? Which one is cool for a teen girl? If anyone has one of these phones from at&t and would be so kind to tell me about it please do!! Thanks so much in advance. =). 10 points to best answer!
