SmarTweak - we like!
16 Jan 2004
Out recently though is SmarTweak, which kicks arse big time! Not only can you change you Startup and Shutdown screens, but pretty much every other screen too ! "Call in progress" screens, sounds, the lot.. Look - just stop reading this and download it. This is an essential tool and it's bloody brilliant - end of. Did I mention that ALL the software was free!!? Well it is, but feel free to contribute to this worthy coder!
Bad point ? Well, although it's free you need to send a code off to an email address and await your serial number so that the coder knows how many people like his software. All good, but this doesn't appear to be automated.. I'm still waiting for mine.. sob..
