I should point out that I wrote my last posting in November during the run up to Christmas. Since then I've successfully installed my application on my own phone, and I've been able to test that it works OK. I've been sitting on my complaint about Symbian Signing since November hoping that things might have changed, but unfortunately that doesn't seem to have happened.
After posting my last entry it appeared that the only route available to me as an independent "home brew" developer would be to release my application as freeware. Symbian signing allow you as a freeware developer to submit your application for signing for free. The Symbian Signed web site states the following
"'Donationware'/'Charityware'/'Honorware' (where the author asks agrees to accept donations if the user wishes to make them) are permitted, provided the full application can be used for free and with no restrictions at all should the user not decide to make their donation - i.e. to all intents and purposes the product can be used freely. " 
So I could release my application for free, I can't charge for it, but I could include a popup that says "If you like my application and find it useful please donate £1/€1.50 to help support future developments". Excellent, well at least now I can see a route to market, with the opportunity to getting something for my efforts.
The same page also states the following:
"Q. How many times can I submit new versions of my application?
A. You can submit updated versions of your application if it has gone through a major functionality update (signified by a change in its version numbers, for example, if your original SIS file was 1,00,0005 and your new SIS file is 1,10,0010 or similar). Updated versions of applications may be de-prioritized at the Publisher Certifier's discretion in relation to new applications being submitted - you should supply details of any changes between versions to help Cellmania prioritize their testing. For example, in the unlikely event of a critical defect fix, this would be considered high priority.
As a guideline you should not submit updated versions more frequently than once every quarter. This helps create a manageable number of applications to test and gives the entire community a chance at equal treatment."
Ok, well that seems fair enough.
Well after a friend read my last blog entry he told me about Antony's open letter to Symbian Signed which was posted on his blog . It makes interesting reading. In it Antony explains that it can often take months to get feed back once you've submitted your application for signing. This is not ideal, but it appears to be the only way.
