Advantages / Disadvantages
iPhone
has a lot of hype, easier to get publicity in the short term
only allows one application to run at a given time
Apple are the gatekeeper
no telephony access from within the SDK
Android
Content providers and intents allow applications to communicate with each other #open intents
GPS as a content provider
Level of phone access for location and telephony e.g. #0870 leads to ability to make services that can only be achieved on mobile
Unregulated marketplace
Potential hardware fragmentation
