Last week Apple released a number updates to its software platforms and applications. The release coincided with the release of the iPhone 4S, the next generation iPhone. I will try to give you an overview of what was released and what are my impressions so far. While I did install iOS5 on an iPhone 4 and an iPad 2, I have yet to hold an iPhone 4S in my hands. Nevertheless I will try to point out some important things about Cupertino’s mobile os.

Notifications are the first one that comes to my mind as they change the way you use your iPhone. Gone are the notification pop-ups that come and then forever disappear. Instead Apple took a lesson from Google’s book and one-up’ed Androids notification center with widget potential. While the only widget in there are Stocks – I believe there is a great opportunity for developers in the future to build amazing apps specifically taking advantage of the new UI. To look at your notifications just swipe top to bottom.

The second one I was looking forward to was iMessage. As I have been a Blackberry user for a long time I have always missed Blackberry Messenger. Now Apple remedied the situation with iMessage. Not only does the iOS messaging app now support texting and mms but also a messenger system between all iOS5 users including iPod Touch and iPad owners. BBM is officially getting its ass kicked. While it may take a while till everyone upgrades it will be much faster than you might expect. One downside of iMessage is that in its default settings Apple decided that if you don’t have a data connection at the time of writing an iMessage your message will instead be sent as a SMS. This has cost me some roaming messages but can be turned off in the settings. I would have preferred to have it off by default.

I have always considered the Lockscreen of the iPhone to be the most under utilized real-estate on the iPhone. We the changes to the notifications that changes as now the Lockscreen can display up to 10 last notifications which makes it immensely useful. Not only that – you can now switch to the Camera app directly from the Lockscreen as well as manage the music you are playing.

iCloud is kind of a disappointment to me. I have expected something fully baked from Apple but I kind of get where they are at. iCloud allows you to wirelessly sync purchased music, apps, pictures and backup your iPhone or iPad to the cloud. This is obviously cool but in this day and age nothing revolutionary. I was actually looking forward to Documents in the Could – a wireless solution that allows me to forget the file system. Don’t get me wrong it works exactly as advertised – on iPhone and iPad. Apparently Apple failed to mention that iWork for Mac is not yet ready for the wireless sync fest and as such the feature Documents in the Cloud is only useful when you are moving between iOS devices. The moment you want to use a Mac it is back to download => edit => upload to iCloud. I bet a new version of iWork with full support for iCloud is in the works as well as an API for developers but until then iCloud is not ready for prime.

Cutting the cord was also a feature I was looking forward to. Not only do I hate syncing via cable but the way Apple implemented wireless sync means I don’t need to explicitly say please sync or back up. When I open iTunes and have my iPhone on the network it will immediately show up and sync. And did I mention iOS updates are from now on incremental and OTA? Awesome.

These are basically the things I find interesting in iOS5. There is plenty more but I have reserved some features for a review of the iPhone 4S. I will try to get my hands on one asap so that I can try out Siri and the new camera. I think these two features alone and the bump in speed make the iPhone 4S a worthwhile upgrade. But that is for another time and another post.
