Reader: How do I unlock my BlackBerry 7520?

BBHub reader Benjamin writes that he just got a Nextel BlackBerry 7520 from a friend.

Benjamin has tried to unlock it, but has not been successful to date.

"I read on the Web that (the 7520) can't be unlocked to operate on (a) GSM network," Benjamin writes. "What about CDMA?"

He hopes that in an implied best-case scenario, it is possible to do both.

Having never been in that position myself, I hand this one off to the assembled multitude of eyeballs that are currently gracing my virtual presence by reading this post.

Well, BBHub readers, have any of you unlocked a BlackBerry 7520? What are your experiences, and advice, if any, for your fellow BBHub reader?

1. You can't unlock a Nextel Blackberry - it's not CDMA network, its iDEN - which is specific to Nextel, unless its a dual mode iDEN & CDMA - however I doubt that. -Sorry.

2. Honestly Russel, if you look a little more on the exact page you list you will find that this handheld is built with and iDen radio, Which means you can't "unlock" it to work with GPRS or CDMA. I can't beleive you run this site and don't know the basics of wireless networks.

3. Okay dude. Out of all the phones to unlock...really? What are you thinking of? I am not going to get technical like the last 2, but really...why would you unlock such a bulky phone in the first place? You won't even get the features of the phone on other networks(push-to-talk and). More power to you if you get it working. =)

6. Can a GSM phone be unlocked for use on a TDMA network? If this were possible, would the Cingular/ATTWS merger have been such a clusterf*ck? iDEN is a specific type of radio transmission, involving encryption, spread spectrum technology, and a number of other factors specific to the iDEN standard. An iDEN phone will work only on an iDEN network. It could be unlocked for Boost, but not all Nextel phones are even locked, many will work with a Boost SIM without any mod whatsoever. That said, to the best of my knowledge, there is only one independent iDEN carrier other than NexTel in the U.S., and they essentially lease and resell NexTel services for the most part (google Southern Linc wireless)
