    Hello... CLICK THIS LINK TO BUY CHEAP VIAGRA!!! (LOL ) Sorry, had no better way of saying long time lurker, first time poster....

    So anyway... I've been an iphone 3gs and now iphone 4 owner...

    But ever since I got the iphone 4 a couple of weeks ago, it's battery would drain in 1 day. I then narrowed it to it being 3g/edge/internet, so I completely turned off internet. If I keep it off, battery is fine. If I turn it on and try to browse using safari it goes into a crazy loop "could not activate celular data" and the bars drop to 1 then back to full (with my carriers name "TIGO" coming and going). This happens randomly, eg I can maybe browse an hour without issues, but then it might happen even just after enabling data network and 3g

    Anyway, I got the phone thru ebay, brand new only opened for JB and unlock ( as it's from ATT).

    The only issue I can think off is that I cut the sim card myself to make it fit, though normal cellphone reception (calls and txts ) is alright (wifi works fine too), problem happens when trying to use 3g/edge.

    Firmware 4.0.1 JB and unlocked with ultrasnow 1.1-1

    Anyhow... i'm in central america hence why my carrier is "TIGO"

    Could not activate cellular data network probably is telling you to check your plan settings on your carrier.

    But even when i set custom APN it happens, also my carrier doesn't use username or password for it's apn, only broadband.tigo.hn when in 3g coverage, when not in 3g coverage it defaults to something like gprs.tigo.hn

    Any other suggestions ?
