Hi all, I'm having a random issue with my Galaxy Portal (T-Mobile UK). Not sure if it's actually a network problem, or a problem with my handset. I can't seem to get an internet connection through any program other than the built-in browser (Google Mail|Twitter|Maps etc) when I'm using mobile data. I also can't connect to any https through the browser (I just get the 'unable to establish a secure connection' error. I am, however, able to browse most other pages normally - but as you can imagine this is quite annoying. When I connect through wi-fi, I can access all pages and use data in all applications normally. I'm using I570EXXJE4, is this a known issue? Would updating to I570EXXJF2 cause more issues than it would fix? All T-Mobile could suggest was to perform a factory reset. I have already tried deleting my APNs and recreating them.
