Hi everyone.

I've decided to be safe than sorry. Although many are saying that iOS4 works well on a 3G, I've read many complains against it. As mentioned by a heavy 3G user, iOS4 is meant for the future, not the past. I think it could support well with 3GS (maybe), but I think there're rather heavy problems on 3G, till the extend of damaging ur 3G set.

Also, I would like to show a big appreciation to those who take the effort to warn others about it and tell your problems. I would like all of u to know that your reviews or postings really matter to all iPhone users out there. You may be unaware those who have benefitted from your comment as they might just read and leave, but I'm happy to tell you that I really appreciate it.

So, my finals words for iOS4 is that, I won't be downloading it. Just be happy with what I'm having and better to be safe than sorry. If wanna use iOS4, save up enough money to get one in the future then.

Here're some posts (from Apply Discussion board) that provide more details (click at the link provided):

iOS4 A Big Mistake
iOS4 Destroyed my iPhone 3G

Just a warning and advice to all 3G users.

Yes, i would like to know this too. Already google and youtube, but i'm confuse.

Thanks

i am a maxis set iPhone 3G user and i updated to iOS4 and feel sluggish in everything and it eats memory so much!   
Then i thought of restore to 3.1.3 but at last it failed due to an error but i forgot the error number,now i gotta restore to iOS4 again.  
pity me and gotta bear with the slow iOS4 at the moment until i found a solution to revert back to 3.1.3.
anybody her able to help out?TQ

what heard from Apple....

The metal side case is acting as antenna......

How come the signal is so weird....strong and weak ????

Maybe the microchip that used to receive signal is from the iphone 3gs
