I think the bigger problem is because, like your aware, that you would need a lot of capital to compete with the major telco/cell companies like the ones listed, it would be more reasonable to create a company that requires less funding by starting with a smaller market to fine tune the company and then seek out larger investors. The problem with this is that even though you won't be initially concerned about the competition from Sprint, Verizon, AT&T, and Tmobile as you would be applying yourself to a less mainstream (aka: different) market, there are still many competitors that have 'fixed' the complaints about the big companies who have a head start over you (ie: Boost Movile, Cricket, even Virgin Mobile). So unless you have an idea superior to these smaller upcoming companies, it will be a very difficult industry to enter in to and raise capital for.

if your on a short budget, check out Freelancer.com. their service allows you to post a project idea (you can choose a marketing genre and even be general and have experts suggest what to do to increase traffic)
freelancers and companies will underbid eachother with a price quote on how much it will cost to complete your project.
Pick a cost effective freelancer with a good user feedback rating.
Freelancer.com is also an escrow service to protect yourself from freelancers obtaining your money without completing the job.
However, the cheap price comes at a cost; in my experience, the quality of the job is significantly less. However, I am still recommending this technique as I have first hand experienced the benefits of outsourcing the work using Freelancer.com for costs at under 1/4th of estimated costs of US services.
Google reacted in a prompt matter to the fix the problem. This is a risk that will always exist when a software becomes open source and you are downloading third party programs - which the Android Market clearly warns you of this risk before downloading the applications. I personally am not holding Google accountable for this incident and am pleased with the quick remedy to the issue.
Although I do find it ironic that Google fixed the problem by using a backdoor 'kill switch' in the android software to fix the backdoor malware of infected users.
