Sloooooow Iphone 3G-How to Speed Up?

[jcarlen]

New to this forum, perhaps someone can help me. I have:
iPhone 3G ATT
Version 4.2.1 (8C148)
Not jailbroken
Modem Firmware 05.15.04
5.6GB available out of 6.9 GB
52 Apps
134 Photos

My 3G seemed to slow down over time so I visited the local ATT store (no Apple store in my town). Knowledgeable guy said I was running old version software and suggested I update it. I did and it is even slower! My apps load so slowly and pages are at glacial speed. What can I do to speed it up?

I read an article about White Door---is this worthwhile to do?
Can I go back to my previous software version?
Should I delete some of my apps and photos?

Any ideas will be appreciated. Thanks.
Jeff

Don't delete your photos. That's not the problem.
You can downgrad your iPhone to 3.1.3.
Just google "iphone downgrade 3.1.3" and you should find some great tutorials for that.
