Apple iPhone App for Hotmail Mailbox

Hey there, We have a client looking for an iphone application which can let users check their hotmail and live mail on the iphone and ipad. There are two other apps out there like it now but we want it to be MUCH better and the key they want is FAST, FAST! We have a list of requirements we need. It's going to be pretty basic: -Read, Reply email -Sync folders, unread mails with hotmail account -Push Notification (an absolute must) -Embedded browser to click on links -view attachments. -compatible with iphone, ipod touch, ipad, and work with the OS 4.0 that is coming out. -AND MORE We need quality work at an affordable price! Should be able to help support app in future as well. Please put 4593 so we know you read the requirements and show us previous app experience. Thanks!!
