Question re: iOS5 on iPhone 4

Will putting iOS5 on my iPhone 4 slow it down at all? I'm weary to install it because back when I installed iOS4 on my 3G, it slowed it down tremendously, almost to the point where it was too slow to use. I know the iPhone 4 has much faster hardware in it than the 3G, but will the same thing happen or is the 4 able to handle it so that it won't make the device slower?

Thanks.

I have not noticed any slowdowns.

According to this iOS 5 review on Engadget.com, it runs "as snappy as ever" on iPad 2 and iPhone 4. I've been running iOS 5 on my iPhone 4 since Friday night and I've noticed some apps open faster and it does seem slightly more responsive. Definitely not slower by any means.

Thanks!

I've not noticed any obvious battery drain differences (apart from geo-fenced reminders - but that's to be expected).

Speed-wise it seems snappier than.

I've had a few app issues where they haven't been updated/tested with iOS5. E.g. spotify - higher CPU use, ok on it's own but can 'stutter' it it's backgrounded.

But all those little bits will work themselves out. Pros still outweigh the cons IMHO

I think it is just as fast as the previous one. In some instance it appears faster, opening web pages for example.

All in all - a tremendous upgrade.

I haven't noticed any changes on mine, either. I have a 4.
