IPhone App Development

i Already finished 70% of the app.
i just need to add few more things that i need an expert to do it


a network connection check once the app start

will add two identical tabs as following

Table Views showing data parsed from json file hosted in my server (duplicate to twitter api feed structure)

- include drag to refresh (current data will be completly removed and load new set of data every time, not like twitter apps to add new data in top of the old loaded tweets)

- if there is a url in the tweet text, it will load thumbnail if its an image or youtube video connecting to embed.ly services (json)

- if its a link, it will be clickable to open in safari

- details view for every tweet to show the tweet information from the table view plus full user information ( parsed from public twitter api) and full image or embed youtube video (from embed.ly)
