iPhone iphone4 remove simlock / jailbreak ?

[ilovecookies]

hey guys!

sorry this is my first apple product, so bare with me

i bought an iphone4 (model A1332) off ebay, which was supposed to be simlock free, but isnt. since i am with different provider (o2) i now need to undo the simlock.

info:
1) i was/am able to start the iphone with an old (deactivated) prepaid simcard i had lieing around from the original provider (t-mobile austria) in case that helps -> i dont get any network connection off the deactivated card though, using my wireless so far
2) the a**hat who i bought the phone off is not responding to my emails, so i cant use the easy way of asking tmobile to remove the simlock
3) software version on the phone: 7.1.1 (11D201), modem firmware: 04.12.09
4) new provider/ simcard i want to use: o2 germany

so, my problems/questions:
a) i want to use my new o2 simcard with that phone
b) id REALLY prefer not to spend money on any of the trick-card-things or unlock services (bought a ****ing old as **** iphone off ebay ffs, tough student life)

do i have to jailbreak the phone to remove the simlock?
if so, what software and version do i use?
is there a way of doing it without jailbreaking it?

BIG thanks to anyone helping me out!

Why not file a claim with eBay that it wasn't unlocked as advertised?

You can't software unlock that BB and I'm not even sure if there's a sim interposer that'll work with that BB

As stated, there is no software unlock or sim interposer to unlock your phone.
Your option is an IMEI unlock from selling carrier if available or after market vendor if available for T-Mobile Austria.

I concur - file a dispute ! Get your money back.
