Hi all, I recently purchased blackberry 8310 (locked to T-mobile Uk) from ebay. Any time I try making conference calls, its says 'The Operation failed' but the second call is connected and the first call is put on hold. I spoke to T-mobile and they said I have to subscribe to blackberry service with them for £7 or £8 before the conference call can work on. Is that really true, please help

Sounds completely wrong to me. Conference calling isn't a BB data feature.

Where exactly does this fail? When you're trying to conference the 2nd call with the first?
