Hey guys! Recently switch to t-mobile in preperation for their 4G network. Yesterday, while on 3G, I attempted to connect to Skype and various other IM apps to no avail. Each time I tried Skype would not log in at all and told me there was a connection issue. I looked further into the issue and understand that T-Mobile may be blocking the use of VOIP apps over their mobile network? Is this correct? I moved to T-Mobile from O2 and never experienced this problem on O2's network. If T-Mobile are in fact blocking applications such as VOIP and IM, is there any work around? Cheers!
