Those of you who know me have most probably realized I talk about a book, the car but I usually say my blackberry, I am indeed a power user of the blackberry and I have it at hand at all times, yes, all times.
In order to make my job easier, I connected it to the BES (Blackberry Enterprise Server) of the company I work for and, this way, I can read my business related emails anywhere and at anytime and it worked fine quite some time.
I learned what "IT policy" means and how it blocks the access of your device to some applications and services but I got round of it in different and always creative ways but slowly, slowly, the restrictions were too much. I could not read my Gmail, I could not check Facebook and I could not report on Foursquare, suddenly, I realized the blackberry was not mine anymore and I decided to get her back to me at the expense, if necessary, to stop reading my business related emails on it.
How? Let me show you:
1) Backup your device using Desktop Manager
2) Download and install JL_Cmdr from here http://www.blackberryfreaks.com/JL_Cmder.html select the option 5) "resettofactory" of the JL_Cmdr menu and follow instructions, it will require remove the battery to reset the device completely.
3) Download and reinstall Desktop Manager from here http://na.blackberry.com/eng/services/desktop/ and make sure you select you want to use your private email and not your business / work email. This option happens to be selectable only at installation time, which is why you must reinstall it.
4) Restore your device from the backup of step 1)
5) Now, the blackberry should be all yours and...
... you should be able to disable the firewall in Options > Security Options > Firewall.
....you could make sure your APN is set in Options > Advanced Options > TCP. If you are uncertain about your APN, username and password, check here http://forum.nimbuzz.com/index.php?topic=545.0;wap2
... you could download latest version of Foursquare http://appworld.blackberry.com/webstore/content/6921
... you could download Google Mobile App in http://www.google.com/mobile/
and through it, the latest version of GMail for Blackberry.
... you could use your Facebook for Blackberry client from ... somewhere ;-)
You will need to remove (and put it back) the device battery after setting are changed, do not be shy on that and, most importantly, be patient, it will work.
I suggest you to read some of this f...ing IT policy in http://www.google.com/search?hl=en&source=hp&q=remove+it+policy+blackberry
And you do not let the IT guys take control of YOUR blackberry, take her back to you ... as I did.
