I’ve had my shiny new iPhone for a couple of weeks now and have enjoyed checking out lots applications and games. He’s just a few of my favourite and most commonly used so far.

Peppermint
Not many of the colour selector / colour palette apps are free, but Peppermint Express is – and the functionality compared to the full paid for version is very good. The app allows you to select a colour from either a colour wheel or sliders, this then generates various sets of palettes depending on if you’re looking for complimentary colours, shades or compound sets of colours, there are 9 different options in total including a custom setting. After finding a palette you like you can save it to one of 3 bookmark slots – these are unlimited in the paid version. Colour theory isn’t a specialist subject of mine, but this app has already helped me to create some really nice palettes for use in websites and logo designs.

DropBox
Thus one was recommended to me by @si on Twitter – I had previously heard of the DropBox service for online backups and file sharing, but I hadn’t tried it and my app enthusiasm was the ideal reason to do so. First of all, DropBox is amazing, I’ve only signed up for the free 2gb version which is plenty of space to play with, and I’ve already found it useful backing up current project files and some of my photography. The iPhone app is free, and gives you access to all the files you’ve uploaded / backed up, and where possible it will give you a viewable version – this works for PDFs and images along with a number of other formats and documents. You can also upload photos from your iPhone – making it easy to transfer images you’ve taken to a computer, considering Apple doesn’t allow you to transfer files via Bluetooth, and I’m pretty lazy when it comes to getting cables out and syncing my phone to transfer an image or two; this is great – it’s quick too, uploads from a computer on a good Internet connection are visibly quicker than other similar services – uploads from your iPhone will depend on your network connection.

Camera Plus and GorillaCam
These free apps enhance the basic camera included on the 3Gs, giving you more options including digital zoom, steadying and rapid multishots.

7.0 Megapixel Camera
One if the only paid for apps in this list (and it was only 59p), it was something I really wanted to try -it has many of the functions of Camera Plus but with the added upscaling of the 3.2mp iPhone camera to a 7mp; which is quite a jump in size. The photos are never going to be DSLR quality, but if you’re prepared for a little noise and not the sharpest of images then the photos are surprisingly good. The only downside is the slow saving of the images, it seems to take forever to write the file.

TweetDeck
I’ve been using the Adobe Air version of TweetDeck on PC and Mac for a while now, I love the fact it links to all my social networking accounts; Twitter, Facebook, Facebook Pages, LinkedIn and MySpace. The iPhone app doesn’t quite have all those networks onboard, but it does have multiple Twitter accounts and Facebook. I haven’t used many of the features yet, although I really like the integrated web browser, which saves on quitting the app and going to Safari to see a web link.

It’s interesting that Twitter has recently purchased Tweetie and will be offering that app for free as a renamed Twitter for iPhone app, I’ll definitely be having a play with that to see if it’s a worthwhile alternative.

MobileRSS
Another essential for me was a stand alone RSS reader, I’ve been using Google’s Reader for a while now so was pleased to find that the free version of MobileRSS works with Google. Set up is easy and it’s really nice to use, reading and navigating through your feeds is easy, it’s a simple app that does one thing really well.

and finally…

Wordpress
This post was written using the free Wordpress app on my iPhone, I thought it was be a nice statement of what’s possible. The app is great, it allows you to easily log into your Wordpress Dashboard using your blog’s URL, your admin username and password. You need to switch on XML writing within settings first, but from there on you have access to your posts, pages and comments – so you can administer a comment, fix a typo on a page or write out a blog post – just like this one.

OK, so there’s one more…

TeuxDeux
I’ve just heard that towards the end of April my favourite to do list manager – Teux Deux – will be submitting their iPhone app to Apple for approval. TeuxDeux is a web based, day specific list manager that is really simple, and for me has been essential in my day to day work flow. I for one can’t wait for the app.
