To put it another way, why learn subject for which there is minimal employment? Or does this return to the earlier topic of pigeon-hole careers? Perhaps we need to focus our children on the ingredients rather than the recipe. www.kartaldepo.com

ut takes it a little further by allowing you to search photos not only by username, but also by tags or a combination of both username and tags. If you find this plugin useful, I would appreciate it if you left a note in the comments.

as to do it, but that doesn't change the essential rationality of wondering why you're doing something that sucks when you could presumably be somewhere else, doing something http://www.bighaber.com

Hello, I have iphone 3g i installed firmware 3.1 by mistake after that i again installed firmware 3.0 after getting errors now i have baseband 05.11.04 something like that, and bootloader 5.90. now I want to unlock my iphone because ultrasn0w is no longer working now.... please help me out.

that doesn't exactly embrace the avoidance of unnecessary intervention.

Maha - September 20, 2009 at 4:16am

The solution is to upgrade to 3.0 OS and then use Ultasnow to unlock..it works for 5.9 and 6.2 bootloader.

Shahzad Riaz - September 21, 2009 at 5:16pm

Still no luck ..i got OS 3.0 and bootloader 6.4... suggestions? cheers.

Hey, i have iphone 3g with fw 3.0. my bootloader is 5.09 and bb is 5.11.07. do you think i can do this to downgrade my bb. Please let me know. And thanks for help.

Maha - October 1, 2009 at 8:29am

Yes It is possible I have OS 3.0 and bb 6.02 *(It was 6.somthing I can't recall). Anyway I used Ultrasnow to unlock my phone. Visit this page and do as they say : http://www.blogsdna.com/3778/how-to-unlock-iphone-3g-30-os-firmware-with-ultrasn0w-06.htm
