A cell phone is an essential product for many, whereas an iPad is not. A phone also comes with a subsidy, an iPad does not. A phone travels with you daily in your pocket, and is more susceptible to damage, an iPad does not and is not (for me at least).
Financially and practically, it makes more sense to upgrade an iPhone well before an iPad. My iPad 2 will be had until I see a reason to upgrade it, which has yet to be presented.
