In April, Steve Jobs was asked about multitasking in iOS 4. “In multitasking, if you see a task manager… they blew it. Users shouldn’t ever have to think about it” was the Apple CEO’s reply.

Unfortunately, I’m increasingly thinking Apple blew it. I’m actually coming round to iOS multitasking in terms of a concept—I really like being able to flick between Safari and Twitter, and especially between Photos and the excellent Pastebot—but I now often enter the task manager and have to think about multitasking.

I suspect the problems are RAM-based, stemming from me having an iPhone 3GS, and playing games. Videogames push iOS hardware like nothing else and are notoriously RAM-hungry. On my iPhone, I’ve noticed performance issues after installing iOS 4, with many games becoming jerky. Sadly, other apps are randomly affected too. Instapaper almost entirely froze last night, and it took about three minutes to get back to the home screen and open the multitasking tray. On removing a few ‘frozen’ apps, everything returned to normal.

This would be fine if it wasn’t for the fact I can’t always do this. I’m getting about one freeze per day on my iPhone 3GS right now, which means in the past week it’s frozen more times than it did over the first six months of usage. I would do a full system restore, but Apple provides no reliable means to restore app data, and I don’t want to lose progress in my installed games.

I’m hoping iOS 4.0.1 is on the way soon and will fix this problem (perhaps by closing long-inactive apps), because it’s a pity that the most robust ‘computer’ I’ve owned is now behaving like a somewhat flaky PC.
