My dad is a Cingular user, he ordered a 8700 for me today.
If I get it unlocked I should be able to use it on Tmobile, correct?

When he ordered it he told them he just wanted to buy the phone without setting up a data plan or altering his contract yet. If we dont add a Cingular data plan will there be any reprocussions to his account?
I might just activate a line with Cingular since I am dropping my home phone and Tmobile coverage in my house sux. The only thing that is holding me back is Cingulars high cost for the BB. On Tmobile I pay $20 for unlimited and $49 for 3000 anytime minutes ( no long distance).
Are there any "combo" plans on Cingular that offer a good value/minutes?
I dont roam or travel....

If you do get it unlocked, it should work fine on T-mobile. If he is purchasing it outright with no activation, then there should be no problems with his account. Cingular doesn't really have ANY good data plans for any of the phone they have. I guess that's the price you pay to be on America's Largets Network (with more bars) lol.

thanx for the response..
TMobile is super cheap and the service is not too bad, other when I lean back on my sofa and my call drops

I read on Hofo that new plans are coming on the 25th, hopefully Cingular has good data/minutes combo.. The 19.99 BB offered by Tmobile is tough to beat!

I agree. T-mobile data plan is rock bottom. The VZW and Cingular networks are larger and will offer the EDGE and EVDO speed but you'll pay a $10 to $15 upcharge for the faster service.

Wondering if anyone has had luck with the 8700G and a T-Mobile SIM card? I tried placing a T-Mobile SIM card into an 8700G and I get SIM card rejected. Anyone else getting this?

You will have an additional problem/hassle on the data side, even with an unlocked phone. The reason is that the IMEI and PIN are registered to Cingular so when you try and use it on T-Mobile they will not accept your PIN IMEI combination until it is released to them by Cingular. Going the other way, I found T-Mobile willing to allow the change when my contract was up. I have no idea how Cingular will act. They may say that if it is registered to them you can only use it with them. In any case they will require that the original purchaser be the one authorizing the change. It is one of the ways they protect your device from being stolen, unlocked and sold for use on eBay to some unsuspecting person.

Thanks man for the reply. Yeah, we had luck with 7290's Cingular (orange) devices right out of the box. We could just take a T-Mobile SIM card and pop it into the Cingular 7290 and away we went. I wish Cingular would become more flexible like T-Mobile is with there customer service.

Unfortunately Cingular started locking phones. My 7290 came unlocked, I was able to sell it for much more than a locked one on eBay as a result.

on Blackberry forums, someone posted that they bought an 8700c from Cingular full retail, called an 800 # got the sim unlock code, input it, put in his tmo sim card, went in and changed to the new pin and imei, and bam he was in business on t-mobile.

I called the 800 # he gave which was 800 335 4685, and they said fax them a copy of the invoice showing that it was bought at full retail price, my imei and email address and they would get me my unlock code for the 8700 also.

The international care rep I spoke to today said that subsidized devices can be unlocked after 90 days.

[takeshi]

GSMphonesource also sells unlocking service for the 8700c via ebay. I can confirm that this works. However, it seems like 8700c distributed via the RIM release party cannot be unlocked this way...

got my 8700c unlocked from GSMphonesource and it works fine

[takeshi]

...and you don't have to mail in your 8700c. You supply him with your IMEI and maybe the PIN (I don't recall exactly) and he emails you the unlock code with instructions or issues a refund if he's unable to provide an unlock code.

[Just2fitz]

So, how long will cingular have the device before tmobile?

[takeshi]

They supposedly have a 90 day exclusive on the 8700. Which doesn't necessarily mean that T-Mo will have it exactly 90 days after Cingular. It took them a while to get the 7290.
