If that is a real 3 - icloud will not even notice it, since OS is outdated and incompatible with icloud. If that is 3gs, you depend on the time you going to be without the phone. If time is long, I would restore from icloud back up and before getting replacement working, back up again, so replacement will be updated with info for the last few days you use that 3gs. If time is short - you can skip icloud restore and not use icloud even to sign in. Alternatively if you sync your info with icloud you can sign in and not back up just sync contacts from the cloud. In that case your contacts and calendars will get updated with info for that short period, but your texts, messages, will skip.
