    So you have the iPad baseband? I'm guessing you didn't install ultrasn0w yet.

    every time i try to get my sim card to work it says searching for a long time and then says no service my wifi is also really spotty (every 5 minutes give or take a few mins it stops and then a couple secs later it comes back on) this gets annoying to because if im downloading something the proccess stops and i have to redownload it. thank you for reading this and for anyone who helps.

    You can't downgrade a baseband and it's much harder to downgrade iOS versions now. Have you tried getting a new SIM card?

    The reason u have ipad baseband 06.15.00 is cuz it was carrier unlocked, so if u updated to iOS 5.0.1 "stock" Apple firmware you've corrupted the baseband. U need to re-flash the iPad baseband & cook/create a custom firmware with redsn)w or sn)wbreeze. Simply put, do the following...

    1. Re-flash iPad baseband.
    2. Use sn0wbreeze to cook custom firmware. (make sure u answer "OLD or NEW" bootrom correctly)
    3. use sn0wbreeze or redsn0w to enter "pwned' DFU, u need to enter "regular" DFU mode to get to "pwned" DFU mode.
    3. Restore via iTunes by holding "SHIFT' on ur keyboard while clicking "Restore" & select the custom firmware that has no stock/lower baseband therefore not corrupting the iPad/higher basebamd that's needed for your unlock. If unlock is not needed, u still must always use custom/cooked .ipsw/iOS firmware cuz of the 06.15.00 iPad baseband that can never be downgraded.

    If ur old bootrom this will be easy without shsh blobs & TinyUmbrella. Or if it's new bootrom & ur below week 135 in ur serial #'2 3rd, 4th & 5th digits, it'll also be ok but if ur new bootroom & newer than week 135 in ur serial number u may be S.O.L.!

    Good luck, I'll check back later & if I'm incorrect anyone please chime in. Or if I think of anything else or u give update I'll help k.
