I have an iPhone 3G, but it's getting old. It no longer supports any new iOS releases, some applications don't work/can't be downloaded, there's a crack down the back of it, etc... So here's what I need: - Email, support for multiple addresses/accounts, and especially IMAP support for Exchange - WiFi - VPN - Calendar support (preferably for multiple calendars) that can be sync'd with Exchange - Phone, SMS, contacts (especially those that can be sync'd to Exchange) - Media player (audio, video) - PDF reader - Office document reader (.docx, etc...) - Web browser (preferably with Flash support as well) - Maps (GPS would be nice) - Telnet/SSH support - Custom application support (a la, iTunes Store), but also something that allows me to write my own stuff and load it onto the device Suggestions?
