I've been looking into iPhone development and may or may not be able to help.
Feel free to drop me an email (me at waynefeltham.co.uk) with some details of what you're thinking of doing and i'll try my best to give you some free feedback.
If it's something that I can do then we can go from there else if it's beyond my capabilities then at least I may be able to apply some do's and don'ts to help you along and maybe find someone else more savvy.
Apologies if this has already been resolved - I realise it's an old thread but I've only just joined and this was the first thread to catch my eye!
Hey Richard, probably too late for this but just in case, I'm an iPhone developer currently in Bath scouting around for one off projects. Feel free to get in touch trithm at hotmail.co.uk
