My iPhone development signing certificate expired yesterday. Thankfully I found that creating a new certificate is quick and painless. Luckily I still have my Certificate Signing Request (CSR).
All you really have to do is upload the CSR. If you don’t have it, you’ll have to create a new one by following the instructions in the certificates tab in ADC’s iPhone center.
After uploading the CSR, you’ll have to approve it by clicking the ‘approve’ button in the certificates tab. In a few minutes, the certificate is ready to download.
