Apps

Hi Apple buddies, I've just bought an iPad 2 64bit off eBay & I've watched loads of videos on Youtube on how to use it. When it came it had the 6.1.3 update installed & I got myself set up with passwords etc.. & introduced it to my Window laptop & iTunes & backed it up. I've now looked at some of the different apps in the app store & tried downloading a few, some paid & some free. I cant really afford to keep buying the apps as its cleaned me out buying the pad so I've been looking at the free apps & it seems that the free ones all come with what I call baggage, like adverts or they want you to sign up for something or " This App doesn't work in your area but pay for it & it will ". I thought about jailbreaking it & putting Cidia on but from what I can understand my operating system is too up to date, I did a jailbreak on my wife's Kindle HD & that was fine. So im looking for advise on how I can jailbreak it & if not do you think there will be a jailbreak 6.1.3 in the near future, or could I download apple apps off somewhere like " PirateBay " & install them manually or is there a site where I can get Apps from that are decent for free ? I am fairly technical but please don't baffle me with science LOL Thankyou
