ME AND MY NEW BABY - IPHONE 4S

I am so loving my new phone right now and who would not be? Finally I get my hands to one of the best phones there is - the IPhone. I am indeed happy as now I can endlessly be online browsing, networking, writing for my blog, taking pics and a whole lot more. I am still exploring it now and filling it with loads of apps there is. Any suggestions of what to install? Cheers - Jericho
