Iphone 3G 16GB All in one again

Finally I got it all work out. My previous post about iphone first generation has come back to haunt me. All because the firmware of the original iphone that has not been build as 'standard' cellular phone.
so I tried the 3G version. I unlocked it using yellowsn0w using firmware 2.2.
a couple days ago I accidentally upgrade my iphone to firmware 3.0.1 and the phone was locked again. I know that 3.0 can do a lot of functionality that a regular cell phone can do. the additional functionality is;

-Forward sms
-copy/paste
-MMS
-tethering internet
-voice recorder
-import contact from sim

above feature was also available from third party vendor. but I like the one from the firmware 3.0

The unlocking process takes about 30 minutes if you have all components correctly.

now I have all feature that I need from a phone.

I need to get the software that can edit office file and send it using email from my iphone....

phieeewww I thought I was going to have the most expensive paper holder
