    Nice software..But i unlocked my mobile using the code..this is the site which provides the unlocking code & instructions for mobiles..It’s useful for me to unlock..
    Is there any software to unlock CDMA mobiles?

  • jason

    Didn’t work on my curve or my storm.
    I went here and downloaded my codes
    it wasn’t free but I got the codes quickly and they worked.
    that’s good enough for me.

  • Gordon

    This voided my warranty!!! my repair claim was rejected and warranty voided after using this. thanks alot! you failed to mention that.
    i bought a new 9700 and just went here and got a code as recommended in the forums.
    now my phone is permanently unlocked and my warranty is still good.

    The sleuths at HowardForums have pointed out that if you’re having issues, you may have to hack around the application’s Configuration.xml file by changing <database name=” and <logging station=”enabled” to “false”. Once again, do so at your own risk! If you’re getting an Oracle error, try disconnecting from the internet. Another thing they’ve pointed out after rooting around the app’s insides is that the Storm might not be supported! One post is already reporting this result, but if any brave souls are willing to try it out on the Storm, please do and let us know how it turns out, good or bad!

  • cheicki

    I got a blackberry curve 8520 and i just want to know if it’s possible to unlock my phone whithout pay …. and if ur answer is yes how can i do this ??? thank’s For your Help !!! i’m french my english is very bad i know but …. loll :)

  • matt

    That file was removed after RIM to legal action.

    Some carriers(in the US) will allow you the ability to unlock your Blackberry for free but the length varies.

    [Contract Plans]
    Tmobile – 90 days & account in good standing
    AT&T – I believe it is 12 Months into your contract they provide the service free.

    Vzw – Unsure
    Sprint – Unsure
    There are a few more hoops with CDMA carriers especially if unlocking the IMEI side(GSM) Side

    If you buy the phone out of contract they are “suppose” to be obligated to unlock it at now cost.

    However if you are impatient like the most of us(me included) I buy an unlock which you can find most places for $20 if you desire it immediately.

    i have a blackberry curve 8350 that was a nextel i currently have it setup with boost mobile but am unable to get internet to work what do i need to do?

  • Dylan

    Almost 100% of those responses are put there by someone advertising an unlocking service.. FUCK YOU GUYS! I have used this software on BlackBerrys for the last year and it UNLOCKS COMPLETELY FREE WITHOUT GOING TO A STUPID WEBSITE OR CALLING SOMEONE! If you have an 8xxx or 9xxx blackberry this is for you! Dont “buy” your unlock when for these particular devices there is a work around!
