Not much new or of substance in this piece in The Globe and Mail, but perhaps additional rationale for not jumping into any long-term wireless contract:

The question will be to decide when/if the September deals are good enough and/or better than will be offered in December. For me that includes possibly paying early termination fees of contracts that expire in Dec and Feb. Or carrying redundant lines until the contracts expire and then porting to a potential new carrier.
