    Hi guys,

    I have an officially unlocked iPhone 3G which I'm using in the UK with T-Mobile.

    Since upgrading to 3.0 I randomly get this message coming up on Safari "unable to connect to cellular network" and I can't access any internet sites. Nor can any apps that rely on internet connection be updated - weather, mail etc!

    I entered all the relevant details into Cellular Data Network and still no luck.

    Any help please? :)

    Have you checked your Cellular Data Network setting? They can be found here:

    Settings>General>Network>Cellular Data Network

    When I upgraded my unlocked 2G iphone last night these were reset to the O2 settings.

    You said you randomly get the message. Do you mean it works some of the time and then stops?

    If so, maybe restoring the software will help.

    Thanks Guys for the replies.

    Well oddly this problem seems to have resolved itself. I'm no longer getting this message. Although the internet does seem a tad slower now on the 3.0 software!

    I might just restore the software as advised.
