branding a phone

[chairsz]

hi all i have a unlocked and unbranded nokia 5230 which operates on the s60 5th platform. i have a rogers prepaid sim card as well as a fido prepaid card. was wondering if there is any software outh there to actually BRAND my mobile to rogers or fido (both in canada by the way) the reason i want to is beacause they both (rogers and fido) charge $2.99 for 20 MB/24 hours of internet/data. and because my phone isnt branded their rule applies exclusively to people with my kind of phone(unbranded)the nokia 5230 has so many internet appz that i weep sometimes not being able to use my phone fully. so i think if i brand it a rogers and the sim recognizes that i could use internet for like $10 a month. so any help is appreciated. my firm ware version is version 20.6 (a nokia 5235 firmware file ) latest though

By the way i have navifirm, JAF, Ovi suite all latest versions,on my windows xp.

That will not work my friend. it is the IMEI that rogers system looks at. So you would have to change that to make it work with that plan.

You want to purposely cripple your phone?!

Actually, ya that will work. All Rogers needs is the SIM card number. Bell is the same way. So long as i use my Bell SIM card, with Bell's APN's, I get Unlimited Mobile Browser.

To load Rogers branded firmware, you'll need to brand the phone for Rogers. You can easily Google a guide on how to do this, and the folks over in the Rogers side of the forum should be able to provide some insight.

If you honestly can't get it to work, PM me, and i'll do my best to help.

i found a diff solution, i went to a rogers outlet on thursday and signed up for a monthly plan. $25 unlimited evenings. couple hundred weekday mins. and a add on for 500MB data plan for 25 a month. theu guy originally told me i wouldnt even be allowed to use my phone online at all since it was non rogers phone . (show's rogers true brains) is 25 a month for 500MB a month a good deal?? havent had a data plan before so wouldnt know in terms of value. wat u tink?

I am not sure that will work.. they use the IMEI not the SIM card. Well worth a try I suppose.

Any results?

They don't use the IMEI. Enough said.

The authentication method for GSM networks is as follows:

1. When the Mobile Equipment starts up, it obtains the International Mobile Subscriber Identity (IMSI) from the SIM card, and passes this to the mobile operator requesting access and authentication. The Mobile Equipment may have to pass a PIN to the SIM card before the SIM card will reveal this information.
2. The operator network searches its database for the incoming IMSI and its associated Ki.
3. The operator network then generates a Random Number (RAND, which is a nonce) and signs it with the Ki associated with the IMSI (and stored on the SIM card), computing another number known as Signed Response 1 (SRES_1).
4. The operator network then sends the RAND to the Mobile Equipment, which passes it to the SIM card. The SIM card signs it with its Ki, producing SRES_2 which it gives to the Mobile Equipment along with encryption key Kc. The Mobile Equipment passes SRES_2 on to the operator network.
5. The operator network then compares its computed SRES_1 with the computed SRES_2 that the Mobile Equipment returned. If the two numbers match the SIM is authenticated and the Mobile Equipment is granted access to the operator's network. Kc is used to encrypt all further communications between the Mobile Equipment and the network.

It doesn't mention the IMEI anywhere in the Authentication process, and since UMTS is based on GSM, it should be similar... This is the only difference...

For authentication purposes, the USIM stores a long-term pre-shared secret key K, which is shared with the Authentication Center (AuC) in the network. The USIM also verifies a sequence number that must be within a range using a window mechanism to avoid replay attacks, and is in charge of generating the session keys CK and IK to be used in the confidentiality and integrity algorithms of the KASUMI block cipher in UMTS.

When a UMTS phone is authenticated with the network for service, it doesnt have anything to do with the IMEI. Nothing whatsoever. If it did, you wouldn't need a SIM card. If you didn't need a SIM card, you'd be using a CDMA based system.
