Well, I’ve reached 100 tweets, from various different devices, and thought I’d jot down my thoughts on the best tools on the various platforms.

First up – the iPhone!  I love the iPhone, and will shortly be upgrading to version 3.0!  Its my favorite platform for twittering generally, as I always have it with me.  I’ve tried a range of tools, but my favorite is Twitterrific, ever since their last version upgrade.  It does absolutely everything I need or want it to do, and is free, if you’re willing to put up with an occasional advert.  I also use Twitterfall, which is a pretty cheap application, and is by far the best tool for monitoring trending topics in the twitterverse.

Next – the BlackBerry.  My BlackBerry is provided by work, and until I got my iPhone was by far the best mobile device I’d come across – its still the best for corporate use and sending emails.  Here, I’ve recently been introduced to the delights of UberTwitter, which is excellent – the location plotting tools are brilliant if a little intrusive if you don’t notice them for the first few tweets!

Of course, posting tweets from the desktop is always useful!  The main Twitter site is always really useful.   The best tool for posting and monitoring tweets used to be Tweetree but I’ve found it a little unreliable of late.  Twitterfall is great on the desktop too, for monitoring trending topics.  Finally, for cordinating a group on Twitter, I’ve found Twibes to be simply great and very easy to use.

Are there other great tools on these platforms?  Absolutely!  These are just the ones that I, as a relative newbie to twitter, have found really accesible and highly useful!  I’d love to hear about others if people want to comment.
