Update on S2 3g problems

[S2JOE]

Firstly hello eveyone!!

I am having an issue with my Samsung GS2.

It seems to have done an update to 2.3.5 over night and since i cannot connect to the 3g. (i am on three).

It continues to go on then back ff. mobile signal full.

I have unlimited data in my mobile contract, however is it possible to get chanrged if ive connected to another network by accident.

If so how do i make sure im on the correct one?

Many thanks
Joe

Could you provide which carrier you are on, since the Galaxy S2 has different variations among the US carriers.
