Im looking at buying a nokia in singapore when i pass through in the next week.

I havnt purchased a phone overseas before with the intention of running on a nz network.

The phone i have my eye on is the n97.

Is getting them unlocked the only difficulty i may run into ? Other than making sure the networks match up.

Or is it only a case of asking the retailer if the phones are unlocked and/or buying from a retailer who isnt a network provider?

And if they are locked, is it best to have it unlocked while im still there?

I have both a working 3g voda sim, and a 2 degrees one.

Thanks

(too many questions at once i know)
