Nec locking up

[Omango]

Hi guys, I have an Nec 606e and only got it over the weekend. Does anyone else have the problem that it locks up when you try to do certain things - like txt mssg

I will take it back to Carphone W/house where I bought it from, but thought I'd throw the problem into the pot before I do to see whether its a common problem.

Cheers Omango
