I installed Scrabble, Facebook, and that roller-ball game (can't remember the name). The apps stall frequently, and I can't even get back to my phone's main screen for about a minute. Hard resets didn't even work. Very annoying. - Bret Taylor

I like the apps, but my phone is a lot more sluggish now, and I am starting to regret my decision to upgrade to the 2.0 software. - Bret Taylor

Nope, I am on the original iPhone. - Bret Taylor

I haven't had a stall or crash yet. I'm on the OG iPhone. - Clay Newton

there seem to be some memory issues. I'm using the original iphone with 2.0 and have had many of the problems with crashes, etc. I just did a fresh restore (not from backup) and things seem a little better. Also, if you're having problems with apps starting and immediately crashing....try removing the app from your phone, and resyncing to itunes. It will reinstall it, and it should be fine. Some sort of security thing that's getting hung up. - shaun mclane

It's buggy on the new phones too. Some apps behave better than others. Does the iPhone have preemptive multitasking? It might not. - Steve Rubel

I'm using an original with 2.0 software. It crashes a lot, but the benefits are large. I was just driving around when I parked and opened up "Boxoffice", found out hellboy was playing near me, and now I'm posting to ff outside the theatre. The apps are making this a cooler though less stable world. - Andrew

Interesting, I've installed about 10 apps on my 16GB iPod Touch and haven't noticed any problems at all. I have had iTunes 7.7 crash twice during syncing, but without any ill effects on either iTunes or my iPod. - Michael Connick

In addition to everything said above, my battery life has gone to hell - Dominik Hofmann

bret, i'm having similar issues -- i think i'm mostly chalking it up to the fact that i installed a fair number of apps, am messing around a lot, etc. think once i settle down, and the apps get a little better, life will be better. (hopefully) - John Lilly

You know what this means right? iPhone == Windows XP. Perfectly fine until you install lots of crappy 3rd party apps. - xero

@xero It feels more like iPhone=Treo 650 - way too many tip calcs, and a few crashes an hour - shaun mclane

Appliances should not crash. A phone is an appliance imo. I really want an iPhone but the battery life issue and stability issues I've been seeing pop up have me rethinking. - xero

I was having the same problem - even top rated apps were crashing everytime. I ended up performing a restore from iTunes and now everything works just fine. - Phil Maxwell

agree ... Apps have been crashing frequently - Nick O'Neill

Brett: just curious, did you go with the preview version on Thursday or the version via iTunes? If the former, you might want to check out: http://www.macrumors.com/2008... - Robert Seidman

My battery life is terrible because I'm addicted to Aurora Feint. - Amit Patel

My iPhone became unstable when I had too many text messages (I get monitoring messages for servers at work), http://mike.stoppelman.com/2008... - Michael

thanks Bret, I was just looking for some reasons... http://friendfeed.com/e... - Orli Yakuel

o thats bc your using the iphone, simply return it to the steve jobs home address for store credit.....dignity non-refundable. - Anthony

Me too. The jailbreak apps were much more stable and useful; now I suppose they'll die off. Super Monkey Ball is the major cause of crashes on my machine; the Google app is #2. - Daniel Dulitz

I'm noticing many hangups and sluggishness but I have nothing to compare it too (first iPhone). Monkeyball wouldn't start a couple of times either. Turning off and back on again resolved all problems. - James Hull

I have found twitterfic and loopt to be the worse. Many times they will automatically restart my iphone. (gen 1) - Tony

Wait, your phone is more sluggish even when you aren't running the apps? That's weird, because I thought the whole design was that apps couldn't run in the background, specifically to avoid impacting the user experience. - ⓞnor

A complete restore definitely seemed to help. We'll see how it lasts... - Bret Taylor

Apps are cool, but battery life seems worse. - Michael Herf

I like Ivan's solution. - David Jeske
