x10 mini stuck in a loop

[#1]

hi there,

i have a brand-new x10 mini that appears to be stuck in a loop. it boots up fine until i get the "data traffic enabled" message in the notification bar and then the phone freezes. sometimes the time continues to update normally but the phone is completely unresponsive, sometimes the phone restarts itself.

if i press the power button and the centre button, the phone reboots but gets stuck in the same cycle.

i have installed the companion software and the phone is detected but cannot connect ...

i have also tried another 02 sim (the phone is locked to o2) without success.

is there anyway to do a hard reset ?

thanks in advance

Sorry...

I mean the middle button (the one with a square above it)

I went down to an SE store today to check how is it that an SE phones' battery cannot be removed. You guys are pure geniuses. There is a small groove that you can lift the cover off of, and the battery is inside.....
