T-Mobile UK 2G Data outage

I’ve been having some issues with my clients’ Blackberry handsets this morning and just received the following update from T-Mobile

I am afraid we have currently got an issue with 2g data services which is affecting all BlackBerry. Its currently affecting central and east London.

I dont have any further information at this time but it looks to only be affecting the BB Curves we have and not the Bolds. Looking at a couple of devices they appear to have GPRS back again but I am still waiting on the OK from T-Mobile to confirm everything is working
