Yes definitely. I have the same exact problem. It usually won't start and takes a couple of tries to actually load. Then when racing, the lag and frame rate issue makes the game agonizing to play.
That has been an ongoing issue with Appsniper for a long time, even before 3.0. That app is pretty much unsupported now. You should delete it and switch to PandoraBox. It's free and MUCH better.
I just downloaded iSR, rebooted my device and it now has Ion Charge lite's logo I hope this wrong app logo business with be sorted in the next update from Apple.
The Enigma Machine. Will appear to load then quit before the game screen appears. Devs are aware and are working on a fix. It's intermittent apparently. (Fast reply too - emailed them today and they got back to me inside a couple of hours)
Kryzer Prologue v1.1 is online now, so the update is available. it solves numerous issues, such as the OS 3.0 framerate problem as well as the sporadic crashs. if anyone still encounters problems, please donĀ“t hesitate to write me a PM =)
The first time I launched GeoDefense under 3.0, the menu came up but then suddenly my dentist called to schedule an appointment But the game probably didn't cause that... I'll test further to make sure it doesn't happen every time Otherwise the game seems OK to me: my progress/scores are preserved.
International Snooker (Big Head Games)- plays like its on fast-forward Developer is already aware and is coding a fix, it's the physics engine that is just running too fast in the 3GS hardware.
When I'm at home in the evening my iPhone pretty much serves as a dedicated Puzzle Quest machine for my girlfriend. On 3.0, unfortunately, PQ always crashes within 5 minutes. My phone is a 3G and isn't jailbroken. I really hope they fix this soon!
My own app, Claustrophobia, has the framerate stutter problem. I submitted the update to Apple a few weeks ago. I noticed people mentioned the code to fix this was easy, but then failed to mention what the code was! Basically, just change the audio session to SoloAmbient. That worked for me.
iCopter Classic (free version anyway) doesn't seem to work at all on OS3 as it either doesn't detect touches at all or like only every 5th one.
For dmbfan and skamando - I'm still having problems with Baseball Superstars in 3.0. It stutters a lot for me on my 3G and new 3GS, both non-jailbroken. Was there something in particular which solved the problem?
This might be unconnected but since OS3 I haven't been able to add anything to my watch list on appsniper by searching. The buttons at the top of the screen aren't there anymore.
