    I unlocked my phone in preparation for some overseas travel. I read about calling Cingular to have them do it, and they obliged.

    So, now I have an unlocked Treo 650. Sooooo.... now what? =) I know I can use prepaid sims now when I travel. I also realize that the phone will be worth more if I decide to sell it for some reason, and that if I wanted to switch providers, I could do that, as long as the new provider used the same type of service, though I'm still not completely clear about all of that. Are there any other benefits to having an unlocked phone?

    Is my phone essentially an "Unlocked GSM" phone now as far as Palm support goes? Can I upgrade to 1.20 firmware? Should I? Shouldn't I? Anything else I should or shouldn't do to celebrate my "unlockedness"?

    Thanks,

    Jonathan

    Congrats. I did the same with my cingular t650 and recently picked up a t-mobile prepaid sim to test. If your regular coverage is lacking, you now have the option of switching sims. The coverage for the other provider might be stronger and you can avoid roaming.

    The sim will come with a completely new phone number. If there are many area codes in your vicinity, you could get another number in a different area code although you cannot use both at the same time.

    This is a great resource:
    http://www.prepaidgsm.net/

    Not sure if the link is acceptable... PM if a mod deletes it...

    My bro will try out one from
    http://www.united-mobile.com/
    HOPEFULLY it works out... free incoming sms and free incoming calls in EUROPE... but read the fine print...

    BUT by you unlocking it, IT IS STILL a BRANDED phone.
    I tried getting a warranty replacement THROUGH palm but when they realized that the IMEI # was a cingular (unlocked) branded phone THEY COULD NOT HELP ME... they referred me to Cingular and I AM GRATEFUL that the process was painless...

    If you WANT to unbrand your phone... then that'll take some work... shadowmite and others have been perfecting that process (as so have others)... a s/w is being developed to help with this...

    BUT I am not sure HOW comfortable you will be experimenting with your firmware and possibly ruining your T650.

    AND they have created a procedure to bring 'bricked' T650's back to life...

    YOU JUST HAVE to love the online support group for T650's... lol

    HTH
    Now it's the WAITING GAME: a GSM Palm Pre
    T680 (COPPER) + Cingular = FUN!!
    My T650 & 6230b and NX70 are retired... =(

    Well, I've been reading through the forums on unbranding, and I think I've ended up more confused than I was when I started.

    My phoen reports Firmware 1.51 and Software 1.17-CNG.

    If I want to unbrand my phone, what are the latest firmware and software I should be looking for? If I understand correctly, there is a 1.20 software, but I'm not sure what firmware I'd be using with that. The latest that I've found reference to in the forums is 1.28, but that seems quite a bit back from the 1.51 that I'm on now.

    Can anyone shed some light?

    I used the "Full, nothing removed, changed files for features. Added SMS emocicons and FAT32. +++Fat32+++" which is a slightly customized version of the newest unlocked/unbraded ROM on my Cingular branded unlocked T650. I've been using it for about a month now without any problems.

    Ah, I did just complete a downgrade/upgrade to the unbranded 1.23 software, then upgraded to the latest and greatest, 1.71 firmware, 1.20 ENA software. Next step will be to play with custom ROMs! =)

    Just to let anyone know who stumbles upon this thread wanting to do the same thing, I followed CodyWalker's instructions found here:

    http://discussion.treocentral.com/sh...ad.php?t=87669

    Instead of getting the 1.13 updater from the Palm website, I grabbed the 1.20 updater, and continued following the instructions.

    It was very easy.

    So, if I understand the terminology now, I now have an unlocked AND unbranded Treo 650.

    Now, like I said, onto custom ROMs. =)

    You are not bound to use prepaid SIMs. Prepaid or Postpaid has nothing to to with Locked or Unlocked status.

    I didn't say I *had* to use prepaid SIMs. I said I *could*. I don't understand your comment. I'm pretty sure the ability to use a prepaid SIM has everything to do with locked or unlocked status.

    Whatever...

    But I meant that the service provider could not lock your phone to use prepaid (or postpaid) exclusively... either your phone is locked (or not).
