what is the difference between the cing and tmobile os?

There are no release notes for the Cingular OS, so we really don't know. The one thing we do see is that the Cingular OS has a downgraded BB Maps application, but I don't see anything different with it.

o thnx i was wondering y every one had a tmobile pearl with the cingular os

The cingular OS is the latest version put out by RIM. It doesn't matter what carrier the OS comes from, it will work with all Pearl's, as long as you delete the vendor.xml file. I for one, always have to have the lastest version of software. That's why I have it installed.

so if u upgrade it will not fff up my fone? im new at this crap and i dont wanna break my fone and can i just wait till t-mo get the new os?

I am running the Cingular release (4.2.0.69) on a T-Mobile 8100. No problems at all.

You can wait, but there is no telling how long until T-mo gets a newer release. And don't worry about f***ing up your phone. You can always wipe it and start from scratch. It's a pretty simple process to do the upgrade.

Just download the upgraded OS and install it on your PC. Then search for the vendor.xml file and delete it. Plug the Pearl in and run App Loader from the Desktop Manager and it will ask if you want to upgrade. The process will take about 30 minutes and at times will look like the phone has locked up. Don't worry, just let it be and it will do it's thing.

could you give me a link for a walkthorugh? or xpalne it urself?
thanx

see above

You can even bring your BB maps app from version .67 if you want to tweak the java folders a little. If you don't know how to do it I suggest leaving it alone but if you like messing with things (like me) it's quite easy. I just copied the lbs.alx file from the .67 folder to the .69 folder and all the net_rim_bb_lbs...cod's (there's maybe 8 or 10) from the .67 java folder to the .69 java folder. When I updated it kept my version. You can do it after the OS install as well and it will upgrade. Why do it? Well....no reason, except I can't leave well enough alone!

True, but just like releasing an updated OS, there must have been a reason to downgrade the BB maps.

do i delete the vendor.xml file from the upgraded os folder on my desktop?

yes

It should be in:
/program files/common files/research in motion/apploader

when i go to the research in motion folder all i see is blackberry and even under that i cant see and apploder file? do i have to open the new os first?

Have you installed the new OS on to your PC?

You are looking in the Desktop Manager directory. Under Program Files, go to Common Files and then Research in Motion.

so im installing it now
this wont give me cingular crap right?
cingular just happen to have it first?

right, to be honest, you probably won't even notice a difference at all. Did you have T-mo version .42 or .64?

.64

just wondering y did u have to delete that file? will i need it later?
