Back in sunny England/Hull now (in comparison to Prague -25 degrees). Only used the phone to call home when I needed to, so shouldn't of ran up too much of a bill. Thanks to everyone who replied with the intent to help.

Has anyone used/can anyone recommend any of the online unlocking services? I've got a Nokia 6700 locked to T-Mobile I want to use as my travelling phone but I'm being quoted £25 by the unlocking place near my office which seems a bit steep.

Can't/won't T-Mobile do it? If not it looks like £10 gets you a code on eBay.

The contract ended a year or so ago, I didn't think to ask for it at the time - I rang T-Mobile about it the other day and they said they couldn't help because the account isn't active, which doesn't sound right to me but I know nothing about these things.

Sounds about right for T-Mob, only way I've done something like this with them is take it into one of their stores and ask if they can help, you'll need to buy a PAYG SIM from them too.

I've managed to sort it with them via their twitter help account, they're charging me £15 which I can live with.

Skygo has been rolled out today for some android devices,works a treat on my galaxy

Cool

Does anyone know why the app needs to be able to 'read sensitive log data'? Is this strictly necessary, or is it just so that Sky can harvest personal information?

Uncool. Appears they have only released it for 2 Android handsets so far and mine is not one of those.
