Most 3G handsets get pretty warm.
As for the vibrate issue did you try toggling the side Vibrate/Loud Button on the Cliq? (It is on the left top side of the Cliq).
yeah, i tried. it was definitely defective. he even downloaded the ring toggle app.
we returned it and then went to the store and picked up a new one. it's completely different. for example:
the cliq vibrates when it's powered on, my brother's didn't
the cliq vibrates when one holds down on a widget, my brother's didn't
the cliq vibrates when the silent switch is put in the down position, my brother's didn't
thanks to everyone for your help. it's been a crazy weekend, trying to figure out if my brother's phone was indeed defective (it's our first time using android, so we didn't know if android had some other smart way of putting the phone into vibrate), trying to find a ups open late enough for us to ship/obtain a tracking number (luckily, staples has a ups inside), and driving to the store the following day to get a new exchange. phew!
i'm headed to the store tomorrow to get a blackberry 9700. with all the negative hardware issues i've been reading about it, i hope i'm not in for another journey!
