iPhone 3GS + iOS 4.0 = Wait for 4.1

Couple weeks ago I updated my phone to the new iOS4.  I was excited to be able to play Pandora in the background while texting (or doing whatever else to enjoy multitasking).  After I download the new version of Pandora multitasking, I was able to run Pandora and do something else on the phone without Pandora stopping.

Besides multitasking there are some other nice features in 4.0 that I like:

• GUI Speed – that is the first thing you notice, things are snappier
• Folders – group application into folders
• App Tray – double click the home button and you get a list of currently running/paused apps that you can quickly switch from
• Camera – got nice update, simulated shutter speed is improved, digital zoom added
• Bluetooth – voice command works via bluetooth now

However, my excitement started to wear thin as I notice some annoyances that keep reoccurring:

• Phone Crash – the most annoying is the phone crashing.  Prior to 4.0, I never had to do a restart on my phone.  With 4.0 I had to do that 3 times already.  Sometimes in the middle of a conversation phone becomes unresponsive and must be restarted
• More frequent drop calls 
• Bluetooth transition slow – now, phone will ring first before it switch to my car

Conclusion: iOS4 is great, but wait for iOS 4.1 if you own the 3GS.  Hopefully that will address some of the issues I mentioned (actually the iPhone4 has its own set of bugs that 4.1 will also address, so just wait).
