Reset Phone from Operator to Generic?

[sc2071]

Hi all,

I've been google searching all night with no luck. I recently bought a Nokia 5230 from T-Mobile, and bought another for my wife from Carphone Warehouse. My phone is all T-Mobile branded, which is annoying enough, but it also missing several functions / applications (e.g. SW Update). My wife's phone is not.

I basically want to remove everything on my phone and get it generic / unbranded like my wife's. Is there any way to accomplish this?

I've tried resetting the phone, and reinstalling the software via Ovi Suite with no luck.

Thanks for any advice!
