App Unlock now lost big "G" GPRS

[Guest yaughan]

Hello,

I've application unlocked my C500 via Orange's developer website. It worked.

Now I have lost the big "G" on the home screen and the internet no longer works - I get the "Connection Error - Unable to place call."

Should I

- hard reset? (annoying)

- ask customer services to do something (what?)

- do something else?

I've searched the archives for an answer and found only others with the same question - please let me know how you solved it when it happened to you!

Many thanks
